The bravo forks is pathetic at Best. But the second set of springs on the fork tubes is a splendit idea if the lack of additional dampening is tolerable. It's simplicity is self evident. Please keep us posted on this because I will do it too if there are encouraging results. It's not easy to locate springs that fit into the bravo fork and actually improve things.
I tried all sorts of home remedies on the existing bravo forks. Before I got the nos set off someone in Seattle, I got ahold of rebuild lowers in the vain hope that somehow the old leaking set of lowers were the problem. Nope with newly rebuild lowers no change. Then I tried all sorts of viscosities and amounts of oils without improvement. Then the new fork never used so the springs were not somehow used too much for the spring to.go away. I can now tell you with complete assurance that the springs don't have any spring to them.i talked to Graham Motzig for his opinion about this several times years ago when we were discussing things about Bravo's and he thought that some people use a really heavy tar that that would somehow impede the open oil baths treatment of springs.I do think Vespa mopeds are having a Renaissance of interest by others. I think the open oil bath does do a little bit of damping maybe. But that's it there's no valve thing in there.It is not a modern motorcycle type of fork where you have a small chamber through which there's an orifice that controls the flow either in one direction or the other and that there's air Chambers above or below all of this. The bravo fork is cute looking but appropriate for 20 mph on a well paved street. whereas with the grande as others have pointed out they are robust and they actually work. my dream would be to somehow sneak in a Fox float fork hidden inside a bravo fork,now if anyone can figure that one out please post the directions or better yet make a second one.
